Meanwhile, new research suggests brains need regular physical activity to thrive.
Life-long exercise habits have shown to lessen the chance of developing Parkinsons and Alzheimers disease.
Imaging studies have found in fitter children – the parts of the brain involved in attention and memory are larger.
David Raichlen, associate professor at the UA School of Anthropology says we’ve known for a couple of decades that exercise can improve brain health but haven’t really understand why.
He says when you exercise you work out your heart, pump oxygen through your blood and organs and build endurance, your brain also coordinates your arms and legs, observes your surroundings, navigates the path, reacts to obstacles and even wanders, focusing on solving problems or what to do after the run.
However, if we engage in those ways, then just like the body, the brain can atrophy.
Mr Raichlen says many past studies have found, for example, that sedentary people show less connectivity and function in the brain and that exercise might protect against memory loss.
